Perception & Stress Flashcards
(72 cards)
Perceptual Organization
Way brain takes info and organizes in a way that makes senses based on pervious experiences
Gestalt
To integrate pieces of info into meaningful whole
visual Capture
Dominance of vision over other sense
Figure and ground
Organization of visual filed into objects( figures) that standout from surroundings (ground) ( one person see bunny, another see bird)
Gestalt grouping principals
perceptual tendency yo organizes stimuli into coherent groups
Proximity
Group nearby figures together
Similarity
Group figures that are similar
Continuity
Perceive conations patterns
Closure
Fill in gaps
Connectedness (continuation)
Spots, lines and areas are seen as unit when connected
Depth Perception
Ability to see objects in 3-D allows us to judge short and long distance
Visual Cliff
By the time a child(small animal) are mobile, they learn depth perception
Binocular cues
Cues in which both eyes are needed to determine the depth of a object
Retinal disparity
Images from two eyes differ, closer the object the lager the disparity
Convergence
Two eyes move inward for near objects (changing what right/left eye see back and forwth)
Monocular cue
used to help determine the relative depth of one or more 2-D objects
Relative size
Assumption that smaller image is more distant (smaller=further)
Interposition
Closer objects blocks the more distant object
Relative clarity
The more focus objects is to eye without accommodation, assumption is is close (BOB ROSS)
Texture gradient
More texture/detail can be see, the closer the object is
Relative height/size
When we assume two items are same size, higher object is perceived as more distant
Linear perspective
Parallel lines converge with distance
Perceptual Constancy
Perceiving objects as unchanging despite change in retinal image (size, color, shape)
Ames Room
Trust what we believe/see to be true
